1. Introduction
Countries nowadays are spending a large sum of money to reach and study outer-space and extra-terrestrial lands. USA
was first country to land on moon but according to Outer space treaty no country can own moon if they have flag on it or
not. Space Exploration was born after World War 2 when USA and Russia were competing to see who is best in
technological aspect. Russia was successful in sending the first artificial satellite whereas USA was successful in first
manned mission to moon. Other countries were also eager to take part in space race, India being one of them.

1.2 ISRO and its history:
The Indian Space Research Organisation (ISRO) boasts a remarkable history of scientific and technological achievements
since its founding in 1969. Under the visionary leadership of Dr. Vikram Sarabhai, ISRO was established with the mission
of harnessing space technology for peaceful and developmental purposes. ISRO's journey began with the launch of its first
satellite, Aryabhata, in 1975, marking India's entry into the space age. Over the years, ISRO has made significant strides,
including developing its own satellite launch capabilities, deploying communication and Earth observation satellites, and
venturing into interplanetary exploration.
It has since become one of the world's leading space agencies, known for its cost-effective and innovative approach to
space missions.
Here are some key aspects and achievements of ISRO:
1. Mars Orbiter Mission (Mangalyaan): In 2013, ISRO successfully launched the Mars Orbiter Mission, also known as
Mangalyaan. It made India the fourth space agency in the world to reach Mars and the first to do so on its maiden
attempt.
2. Chandrayaan Missions: ISRO has launched two lunar missions. Chandrayaan-1, launched in 2008, made significant
discoveries about the presence of water molecules on the Moon. Chandrayaan-2, launched in 2019, included an
orbiter, a lander (Vikram), and a rover (Pragyan), although the lander encountered difficulties during its descent.
3. Aditya L1: Aditya-L1 mission is a planned solar observation mission by the Indian Space Research Organization
(ISRO). The primary objective of this mission is to study the Sun, particularly its outermost layer, called the corona,
and the impact of solar activities on Earth's climate
4. Navigation: ISRO developed the Indian Regional Navigation Satellite System (IRNSS), later renamed NavIC
5. (Navigation with Indian Constellation). NavIC is a regional satellite navigation system that provides accurate
position information service to users in India and surrounding regions.
6. Earth Observation: ISRO operates a series of Earth observation satellites that provide crucial data for applications
such as weather forecasting, disaster management, agriculture, and resource management.
7. Communication Satellites: ISRO has launched numerous communication satellites, such as the INSAT and GSAT
series, to enhance India's telecommunications infrastructure and provide connectivity services.
8. International Collaborations: ISRO collaborates with various international space agencies and organizations on
joint missions and projects. It has also launched satellites for other countries as part of commercial launches.
1.3 Chandrayan Mission:
The Chandrayan missions are lunar exploration missions conducted by the Indian Space Research Organisation
(ISRO). There have been three Chandrayaan missions:
1. Chandrayan 1:
Chandrayaan-1 was India's first lunar exploration mission, launched by the Indian Space Research Organisation
(ISRO). It was launched on October 22, 2008, and it marked a significant milestone in India's space exploration efforts.
The primary objectives of Chandrayaan-1 were to:
a. Conduct high-resolution remote sensing of the moon in visible, near-infrared, and X-ray spectra.
b. Perform chemical and mineralogical mapping of the lunar surface.
c. Study the moon's topography and terrain.
Chandrayaan-1 was equipped with a variety of scientific instruments, including the Moon Impact Probe (MIP), which
was designed to impact the lunar surface and provide additional data. However, the MIP was released prematurely
during the mission, and it was not able to achieve its intended purpose. Despite this setback, Chandrayaan-1 was able
to collect valuable data about the moon's surface and composition during its mission. One of its most significant
discoveries was the presence of water molecules on the lunar surface, particularly at the moon's poles. This discovery
was important because it suggested the possibility of water ice on the moon, which could be a valuable resource for
future lunar exploration. Chandrayaan-1's mission was cut short in August 2009 when ISRO lost contact with the
spacecraft. Initially thought to be lost forever, NASA's Lunar Reconnaissance Orbiter (LRO) discovered Chandrayaan-
1's remains in lunar orbit in 2016. Chandrayaan-1 paved the way for subsequent Indian lunar missions, including
Chandrayaan-2, which aimed to build upon the knowledge gained from the first mission and included an orbiter, a
lander (Vikram), and a rover (Pragyan). Chandrayaan-2 was launched in July 2019.

2. Chandrayan 2:
Chandrayaan-2 is India's second lunar exploration mission, following the success of Chandrayaan-1. It was launched
by the Indian Space Research Organisation (ISRO) and was designed to build upon the knowledge gained from the first
mission while also expanding India's capabilities in lunar exploration. Chandrayaan-2 had three main components:
A. Orbiter: The orbiter is designed to orbit the Moon and conduct remote sensing observations. It carries a suite of
scientific instruments to study the Moon's surface, mineral composition, and exosphere. The orbiter is intended
to provide valuable data about the Moon from lunar orbit.
B. Lander (Vikram): The lander, named Vikram, was designed to make a soft landing on the lunar surface near the
South Pole of the Moon. It was equipped with scientific instruments to study the lunar surface and conduct
experiments. The goal of Vikram was to explore the surface in close proximity and provide data about the Moon's
geology.
C. Rover (Pragyan): The rover, named Pragyan, was housed within the lander Vikram. It was designed to traverse
the lunar surface, analyze soil samples, and perform experiments. The rover was intended to enhance our
understanding of the Moon's composition and surface properties.
Chandrayaan-2 was launched on July 22, 2019, aboard a GSLV Mk III-M1 rocket. While the orbiter successfully
entered lunar orbit and continues to study the Moon, the lander Vikram encountered difficulties during its descent to
the lunar surface. Unfortunately, it lost communication with ISRO mission control, and its status remained uncertain
for some time.
Despite the challenges with the lander, the Chandrayaan-2 mission is considered a significant achievement for ISRO,
as it demonstrated India's capability to send an orbiter to the Moon and attempt a soft landing. The orbiter continues
to send valuable data back to Earth and contribute to our understanding of the Moon. Chandrayaan-2 represents
India's continued commitment to lunar exploration, and it has paved the way for future missions to explore and
utilize the Moon's resources.
3. Chandrayan 3:
 Demonstrate the ability to land a spacecraft on the Moon
 Explore the lunar South Pole region, which is relatively unexplored
 Study the lunar surface and subsurface
 Search for water and other resources on the Moon
The Chandrayaan-3 mission is a significant milestone for India's space program. If successful, it will make India the
fourth country to land a spacecraft on the Moon, after the United States, the Soviet Union, and China. The mission is
also significant because it is the first time that India is attempting to land a spacecraft on the lunar South Pole. The
South Pole region is of particular interest to scientists because it is thought to be home to water ice and other
resources. The Chandrayaan-3 mission is expected to last for about 14 days. The Vikram lander will conduct
experiments on the lunar surface, and the Pragyan rover will explore the surrounding area. The Chandrayaan-3
mission is a challenging one, but it has the potential to make major contributions to our understanding of the Moon. It
is also a sign of India's growing ambition in space exploration.
2. Chandrayaan-3 in Detail:
Chandrayaan 3 was planned after the unsuccessful landing of lander of Chandrayaan-2. On 22 July, 2019, ISRO launched
Chandrayaan-2 mission with Lunch vehicle mark-3(LVM3) which consists of orbiter, lander and rover. Orbiter was
successful in setting up orbit around but during landing, ISRO lost contact with lander deviating from its original trajectory
and crashed.
After the first try, ISRO launched theird edition to chandrayaan mission on 14 July, 2023 and lander successfully landed on
23 august, 2023.
Chandrayaan-3 is an Indian lunar mission that was launched on 14 July 2023. It is the third Indian lunar mission, and
the successor to the Chandrayaan-2 mission, which was launched in 2019 but failed to land on the Moon safely.
Chandrayaan-3 consists of a lander and a rover, but it does not have an orbiter. The lander is named Vikram, and the
rover is named Pragyan. Vikram is scheduled to land at the Shackleton crater, which is located near the South Pole of
the Moon.
The main objectives of the Chandrayaan-3 mission are to:

Chandrayaan-3 comprises three main components: a propulsion module, lander, and rover.
LMV3 was the main spacecraft consisting of Propulsion module, Lander and Rover.
We will calculate equations and distance of LMV3 of Chandryaan-3.
Elements of Chandrayan-3:

4. What is a Maneuver:
In space exploration, maneuvers refer to planned and controlled changes in the position, velocity, or trajectory of
spacecraft. These maneuvers are critical for various aspects of space missions, including:
1. Orbit Changes: Spacecraft often need to change their orbits for a variety of reasons, such as getting into the
desired orbit around a celestial body (e.g., Earth, Mars, or the Moon) or transitioning between different phases of a
mission. These maneuvers are accomplished by firing onboard thrusters or engines at specific times and
directions to alter the spacecraft's velocity and trajectory.
2. Rendezvous and Docking: When two spacecraft need to meet and dock in space, precise maneuvers are required
to ensure a safe and accurate approach. These maneuvers involve adjusting the relative positions and velocities of
the two spacecraft.
3. Landing and Descent: For missions involving planetary or lunar landers, maneuvers are essential for controlled
descent and landing on the target body. These maneuvers often include course corrections to ensure a precise
landing location.

4. Trajectory Corrections: During long-duration missions, spacecraft may need to make periodic trajectory
corrections to account for variations in gravitational forces, errors in navigation, or to optimize the mission's path.
5. Flybys and Gravity Assists: Some missions use the gravitational pull of celestial bodies (e.g., planets) to change
their trajectory or gain speed. These gravity-assist maneuvers are carefully planned to maximize the mission's
efficiency.
6. Station-Keeping: In missions involving multiple spacecraft or satellites in close proximity, maneuvers are
performed to maintain a stable position relative to each other, such as in Earth observation satellite constellations
or space station docking.
These maneuvers require precise calculations, careful planning, and often real-time monitoring and adjustments to
ensure the success of a space mission. They are typically executed using onboard propulsion systems and are a
fundamental aspect of space exploration and navigation.
5. Elliptical Orbit:
Elliptical orbits are a common type of orbit used by spacecraft for various purposes, including Earth observation,
communication, scientific exploration, and interplanetary missions. Here are some key aspects of elliptical orbits for
spacecraft:
1. Definition: An elliptical orbit is a type of Keplerian orbit, characterized by its shape, which resembles an elongated
or flattened circle. In an elliptical orbit, the spacecraft follows an elliptical path around a celestial body, such as a
planet or the Sun.
2. Foci: An elliptical orbit has two foci (plural of "focus"). These foci are located along the major axis of the ellipse.
The sum of the distances from any point on the orbit to the two foci remains constant.
3. Semi-Major Axis: The semi-major axis (denoted as "a") is half the length of the major axis of the ellipse. It is a
critical parameter that determines the size of the orbit. The semi-major axis also defines the average distance
between the spacecraft and the central body.
4. Eccentricity: Eccentricity (denoted as "e") is a measure of how elongated the ellipse is. It ranges from 0 (for a
perfect circle) to 1 (for a highly elongated ellipse). The value of eccentricity determines how much the orbit
deviates from a circular shape. Elliptical orbits have eccentricities between 0 and 1.
5. Periapsis and Apoapsis: In an elliptical orbit, the point closest to the central body is called the "periapsis" or
"perigee" (for Earth orbits), and the point farthest from the central body is called the "apoapsis" or "apogee" (for
Earth orbits). The distances from the central body to the periapsis and apoapsis are critical parameters for
mission planning.
6. Orbit Dynamics: In an elliptical orbit, the spacecraft's speed varies as it moves along its path. It travels faster at the
periapsis and slower at the apoapsis. This variation in speed is governed by Kepler's laws of planetary motion.
7. Orbit Changes: Spacecraft in elliptical orbits can change their orbit shape and size by performing orbital
maneuvers. These maneuvers may involve firing thrusters to increase or decrease speed, change the orientation
of the orbit, or transfer to a different type of orbit.
Elliptical orbits offer flexibility in mission planning, allowing spacecraft to meet specific objectives, such as close
encounters with celestial bodies or efficient use of propulsion systems. They are commonly used in space
exploration and satellite operations.

6. Why I chose this Topic?
I chose to research Chandrayaan III's journey because of my love for space science and the universe which has
transformed me as a person completely. I draw inspiration from various individuals the works of whom encourage me
to explore the cosmos as well. This mission, to me, represents not only India's remarkable step forward in space
exploration but a subtle opportunity to inspire the young, brilliant scientists of our future - to urge them to try their
best to contribute to the ever-expanding frontier of cosmic knowledge. This paper is my humble contribution to this
endeavor, and I aim to distinctly analyze the remarkable journey of Chandrayaan III and portray its significance in
furthering our understanding of the universe.
7. Calculation and Orbital Equations:
Equation for Earth Maneuver and Lunar Maneuver were calculated by plotting points on desmos with Earth and Moon
radius taking under consideration:
Radius of Earth= Re=6378 km
Radius of Moon=Rm=1737 km
Assumption: Earth and Moon are taken as perfect circle but in reality they are not perfect circles.
For Earth related orbits and equation, center is taken as center of earth (0,0).
For moon related orbits and equation, center is taken as center of moon (0,0).
Orbit distances are given in table under mission profile. Distance is taken from earth surface so we consider a point on
circle as observation point.

2b=b1+b2+2Re
And Value of (h,k)is calculated which tell how much there is deviation from center(0,0).

Value of h=0 because k>>>>>h, so there is no change in vertical path.

equation of ellipse for each maneuver. Our research paper is relevant in the field of astrophysics and mathematics for
Chadrayaan-3. We are successfully in calculating 11 equations of orbits covered by LMV3. We have successful
calculated total distance covered by KMV3 that is 1.47835 X 1011 km . From this data, we also got average speed of
LMV3 for the whole journey, 1.987 x 108 km/hr.
Concluding this research paper, by slogan given by honorable Prime minster of India Shri. Narendra Modi: “ Jai Vigyan,
Jai Anushandhan” which means victory over research is victory over science.
